Customer Service Representatives

ESU proudly boasts the largest staff of cross-trained customer service associates in the marketplace. ESU’s entire staff of CSRs is trained on all product lines and fully capable of servicing quotations, purchase orders, expediting, and providing technical assistance. With extended customer service hours of 6:00am to 6:00pm every business day, ESU provides its customers and end-users with a superior level of service and sales support.

Although all CSRs are cross-trained on all product lines, each manufacturer is assigned an inside sales coordinator. The designated sales coordinator serves as the primary contact for the principals’ administrative personnel and is responsible for the daily administration of the product line. This includes managing all quotations, maintaining and distributing sales literature, and updating the sales staff with changes to policies, procedures and market conditions.


In an effort to maximize end-user demand and specification for our products, ESU maintains a specification marketing program focused on consulting engineering firms, architects, original equipment manufacturers (OEM) and maintenance, repair and operation (MRO) personnel. An overview of specification activities includes the following:

  • Maintain specifications with consulting engineering firms, with management involvement at key/major firms
  • Construction project targeting and tracking
  • New business opportunities for OEM and MRO accounts through database marketing and a on staff OEM/MRO specialist
  • Energy management specifications for energy-service companies (ESCO) and lighting maintenance contractors (LMC)
  • Contractor specifications and maintenance of relationships with major contractors


ESU is very active in the promotion of its organization and its manufacturers through an aggressive marketing and advertising campaign. ESU is a regular advertiser in the following trade publications:

  • The Electric News, Pacific Edition covering Arizona, California, Hawaii and Nevada
  • The Electric Times of Arizona
  • The Electrical Distributor magazine
  • The Electric League of Arizona Annual Buyers Guide

In addition to regular advertising, ESU also markets its manufacturers through regular promotions including the ESU corporate jacket promotion, catalog stickers, on-hold advertising featuring new products each month and joint promotional programs with its manufacturers.
